The kinetic sculpture, titled Concentric Wave, was permanently sited at The Harley Gallery, Worksop, Nottinghamshire and straddled a four metre circular pond at the bottom of a red brick lined amphitheatre in the gallery garden.

“Conceived as a mechanical reflection of the water below, the piece is about simplicity, repetition, rhythm and balance.” Smith explains.

Movement triggered sensors activate the piece as people approach. The ball gently rises and falls seemingly activating a mechanical ripple through the eighteen concentric rings. In reality cams, rods and gravity precisely control this motion.
